Recommended: Water crisis and its solution
Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes to 5 percent. (Baroudy 2005, 15)
And this problem seems to become worse day after day. From the middle of the XX century demand on freshwater has increased three times. And this statistics will continue to grow with population rise and industrial development. Water scarcity is a huge problem, because it may have a number of economical, social and political consequences. Bad harvest and famine are one of them (Brown 2008, 16). Also lack of water for elementary daily needs will lead to insanitariness. This will increase risk of spreading such diseases as typhoid, cholera and dysentery (10 facts about water scarcity 2009). Also disastrous water shortage in the Middle East may change existent struggle into regional conflict. It is evident that this problem needs to be immediately solved.
There are few possible solutions and some of them are already applied by this time. All of them have some advantages and disadvantages. The target of humanity is to find the best one.
Firstly, one possible solut...

Water shortage in arid and semi-arid regions and declining its availability to a crisis ...
Introduction on Water It covers 70% of our planet, makes up 75% of our body, it is necessary for survival and it is declining at a rapid rate (http://www.sscwd.org). It is water. Unfortunately, clean water is rare, almost 1 billion people in developing countries do not have access to water everyday. “Yet, we take it for granted, we waste it, and we even pay too much to drink it from little plastic bottles” (The Water Project). Use of earth’s natural resources should be seen as prosperity, although it is taken for granted, every aspect of daily life revolves around the environment, forcing water conservation to be necessary for future on this planet.
Presently, in the USA the California state is starting suffer with water crises. Therefore, the state started planning many desalination plants. There are three current desalination station, and the government is planning more fifteen. Figure 9 shows the desalinations plants in the California state. There are many critics about the desalinization plants.20 Arguments use against the plants are which use huge amounts of energy, and is very danger for the marine life.20 Desalinated water construction costs approximately $2,000 an acre foot.20 In addition, to produce one gallon of drinking water need two gallons of seawater.20 This process consumes about 38 megawatts to remove 100 million gallons of seawater per day.20

In addition to the land conflict that Israelis and Palestinians are experiencing, water tension between the two parties has become a growing concern. 2 Palestinian territories, West Bank and Gaza Strip, are very dependent on Israel’s for water, as “Israel controls the greater part of the Jordan River basin and the West Bank’s aquifers” (Isaac) and because militant authorities have restricted the usage of water in many Palestine homes, causing water scarcities. The Israel-Palestine water conflict is an example of economic water scarcity because it shows how water is available locally, but it not accessible for human, institutional or financial capital reasons due to government intervention, or lack of infrastructure causing people to use rivers and lakes as their source of water.
Fred Pearce’s book When The Rivers Run Dry argues that humanity is facing a substantial water crisis, both now and in the decades to come. He first notes worldwide water patterns and examines worldwide water economics. Then, he spends much of the rest of the book discussing specific places where water supply is currently an issue and correlating those places to those worldwide trends. Pearce first discusses the world’s groundwater crisis, looking at overuse of groundwater in India, the Great Plains, and the Middle East; Libya’s scheme to bring desert groundwater to its people, the Great Manmade River); and arsenic poisoning of wells in Bangladesh. He then moves onto the world’s devastation of wetlands and other wet places across the world, looking at how humans have targeted wetlands like the fens of Great Britain, the Sudd of Sudan, the Pantanal of Brazil, and the Okavango Delta in Botswana.
With ever growing issues like climate change and pollution, poorer countries are being severely affected by water shortages, but with these problems even wealthier countries are dealing with water scarcity.

This allows the most efficient way to absorb the wealth of the ocean water. Desalination of salt water is perspective because a large numbers of arid areas adjacent to ocean coast, or are close to it. Thus, ocean and sea water are raw materials for industrial use. Nowadays exist about 30 ways to of desalination of sea water. All methods of turning salt water into fresh water require more energy. In general, the share of electricity accounts for about half of the cost of desalination, the other half goes to the maintenance and depreciation of equipment. So, the cost of desalinated water depends mainly on the cost of electricity. (FWR, 2011) However, where is a lack of fresh water and exist the conditions for the desalination the cost factor recedes into the background. In some areas desalination is environmentally advantageous than bringing water from far away. Desalination of salt water is developing quite rapidly. As a result, every two or three years, the total capacity of installations
Water is one of the most important and basic natural resources. Water is not only one of the most essential commodities of our day-to-day life, but the development of this natural resource also plays a crucial role in economic and social development processes. While the total amount of water available in the world is constant and is generally said to be adequate to meet all the demands of mankind, its quality and distribution over different regions of the world is uneven and causes problems of scarcity and suitability. It is therefore imperative that man develops, uses and manages this scarce commodity as rationally and efficiently as possible.
Freshwater in the world makes up only a small portion of water on the planet. While the percentage of water in the world is nearly 70%, only 2.5% is consumable. Even further, only <1% is easily accessible to basic human needs. According to National Geographic, “by 2025, an estimated 1.8 billion people will live in areas plagued by water scarcity, with two-thirds of the world's population living in water-stressed regions as a result of use, growth, and climate change.” With this current trend, water will become more immersed in environmental, economic, political, and social changes. Many of these in later years shall need to be addressed as tension rises:
Freshwater is quite scarce, but it is even scarcer than one might think: about seventy percent of all freshwater is frozen in the icecaps of Antarctica and Greenland and is unavailable to humans. Most of the remainder is present as soil moisture or lies in deep underground aquifers as groundwater. It is not economically feasible to extract this waster for use as drinking water. This leaves less than one percent of the world’s fresh water that is available to humans. It includes the water found in lakes, reservoirs, groundwater that is shallow enough to be tapped at an affordable cost. These freshwater sources are the only sources that are frequently replenished by rain and snowfall, and therefore are renewable. At the current rates of consumption, however, this supply of fresh water will not last. Pollution and contamination of freshwater sources exacerbate the problem, further reducing the amount of freshwater available for human consumption. Something must be done if humans want to even survive in the near future: the lack of clean drinking water is already the number one cause of disease in the world today. The first step is worldwide awareness of the water crisis: governments and the citizens they govern worldwide need to know about this problem and be actively involved in solving this problem.

While the earth may be mostly water, only about 2-1/2 percent of it is fresh water. Of that 2.5%, even less is considered to be potable. Potable water is water that is considered to be safe to drink and cook with. While many countries are working to build water treatment plants, the fact is that due to changes in the climate the amount of rain and ice melts from winter have dropped off and lowered the reserve supplies of freshwater to be treated. There are initiatives to educate and regulate the use of water in the world, as well as exploration into the technology of water farming in arid countries
